We agree that traditional "affiliate" deals are often flawed because promo codes fail to track every sale. IP-matching technology solves this by attributing every listener who converts, even if they don't use a code. We invite you to test this "new way" for a few campaigns—the results speak for themselves, and usually = much more $$ than a traditional affiliate program!
See real screenshot from Podscribe dashboard above. Whereas promo codes only attributed 598 conversions, IP-matching shows the true impact of the campaign as 24,000 (!!) conversions.
